Application filed April 19, 1909. Serial No. 490,809.

To all whom it may concern:

Be it known that I, OLIVER Born, a citizen of the United States,residing at Spencerville, in the county of Allen and State of Ohio, haveinvented certain new and useful Improvements in a Combined Hay Rake andLoader; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in combined hay rakes andloaders.

The object of the invention is to provide a self raking hay loader bymeans of which the hay is gathered and loaded into a wagon to which themachine is attached.

A further object is to provide a device of this character having meanswhereby the hay when elevated by the loader will be spread out ordistributed over the hay rack on the wagon.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings, Figure 1 is a side view of a combined hayrake and loader constructed in accordance with the invention, showingthe same in position at the rear end of the wagon body, a portion of thelatter being shown in dotted lines; Fig. 2 is a top plan view of thesame; Fig. 3 is a vertical longitudinal sectional view on the line 33 ofFig. 1, looking in the direction of the arrow.

Referring more particularly to the drawings, 1 denotes the supportingframe of the machine in the forward end of the lower portion of which ismounted an axle 2, on the ends of which is fixedly secured frontsupporting wheels 3. The rear end of the frame 1 is provided withswiveled supporting wheels or casters 4:.

In the rear portion of the frame 1 is arranged an inclined elevatorchute or trough 5, the sides 6 of which are continued forwardly at theupper end of the chute and said sides have on their lower edges inwardlyprojecting guides 7 between which is slidably mounted a slatteddistributing apron 8. The slatted apron 8 is adapted to be reciprocatedin a manner hereinafter described.

In the lower portion of the rear end of the machine is revolulolymounted a conveyer operating shaft 9 on which, adjacent to its oppositeend, are fixedly mounted sprocket wheels 10 with which are engagedchains 11 of the endless conveyer or elevator 12, which consists of aseries of cross bars or slats 13 each of which is provided on one sidewith a series of teeth 14 which are adapted to gather the hay fromground and draw the same up the inclined chute or trough and onto theslatted apron 8 by means of which it is evenly distributed on the hayrack on the wagon. The upper stretch of chains 11 of the conveyer passesover sprocket wheels 15 on a shaft 16 revolubly mounted in the upperends of the sides 6 of the chute and the lower stretch of the chainspasses over curved guide flanges 17 arranged on the inner walls of thesides below the sprocket wheels 15. The chains 11, after passing overthe sprocket wheels 15 and flange 17 continue to the end of theforwardly extended sides of the chute and pass around guide pulleys 18and 19 mounted on transversely disposed shafts 20 and 21 which aremounted in suitable bearings in the forward-end of the frame and sidesof the chute.

On the rear end of the lower portion of the frame 1 is arranged a rakesupporting frame 22 in which is adjusta'bly mounted a spring toothedrake 23 which is adapted to trail behind the lower end of the conveyingand elevating mechanism to gather any hay which is not taken up by theelevating mechanism. The rake 23 is'provided on one end with anadjusting lever 24by means of which the rake may be raised or lowered toinoperative or operative positions. The lever is adapted to be engagedwith a notched rack bar 25 by means of which the rake is held in itsadjusted positions.

In addition to the rake 23, the machine is provided with additional siderakes 26 which are adjustably mounted in a frame 27 one end of which ispivotally connected to the side bars of the main frame, adjacent to thelower end of the chute 5, while the outer ends of Said rake frames areloosely I held at the desired angle at the sides of the connected to andsupported by caster wheels 28. The side rakes are provided withadjusting levers 29 which are adapted to be engaged with segmental racks30 on the frames 27 whereby the rakes may be held in their adjustedpositions. The side rakes 26 are provided to rake up and throw the hayalong the sides of the machine beneath the same and into the path ofmovement of the conveyer by which it is gathered up and carried to thewagon. The side rakes are machine by means of connecting bars 32, theouter ends of which are pivotally secured to the outer ends of the frame27 while their inner ends are provided with a series of apertures bymeans of which the bars are adjustably bolted or otherwise secured tothe frames of the machine.

In the lower rear portion of theframe 1 at the lower end of the conveyerchute 5 is revolubly mounted the clearing roller 33 provided with aseries of radially projecting teeth or pins 34 which work between theteeth on the slats of the conveyer and between curved teeth 35 formed onthe lower end of the bottom of the chute, as shown. The clearing rolleris provided to prevent the hay from bunching and dragging at the rearend of the machine.

On the outer ends of the axle 2, between the wheels 3 and the sides ofthe frame, are mounted sprocket gears 36 which are connected by crosschains 37 to sprocket gears 38 on the ends of the shaft 9 therebyproviding for the operation of the conveyer by the axle 2 and the wheels3. The chains 37 also pass over sprocket gears 39 on the ends of theclearing roller shaft, thereby operating said roller. The upper stretchof the chains also engage idle supporting gears 40 which are mounted onthe stub-shafts on the adjacent sides of the lower portion of the frame1.

In the upper portion of the frame is revolubly mounted an apron drivingshaft 41 on the outer end of which is fixedly mounted a pulley 42 whichis connected by a cross belt 48 to a small pulley 44 on the outer end ofthe upper conveyer shaft 16, whereby the motion is imparted to the apronoperating shaft. On the inner end of the apron operating shaft 41 isfixedly mounted a sprocket gear pinion 45 around which passes a sprocketchain 46 which also engages a sprocket pinion 47 which is suitablymounted in a bracket 48 on the lower portion of the frame 1 adjacent tothe lower end of the underside of the chute 5. The rear end of theslatted apron 8 is loosely connected to one side of the chain 46 bymeans of a pitman rod 49 whereby when the chain is operated through thepinion 45 and pulleys 42 and 44, the slatted apron will be recipro:cated or moved back and forth lengthwise l between the forwardlyextended sides of the conveyer chute, thus distributing the hay onto therack of the wagon, over which said forward end of the conveyer chuteprojects;

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claims.

Having thus described my invention, what I claim is: a
